Zooming in on the shed, there is a shunter 269 066 , and an undetermined Class 86 (Floyd has 8 operating Class 450 locomotives - 86215, 86217, 86218, 86228, 86232, 86242, 86248 & 86250, with 86424 for spares, the latter still believed to be in yellow colours.
Turning to another angle, another Class 86/2 is seen, and what at the time I though was one of the Floyd Class 56's. However examination today finds that this is a Class 47, so must be 47375 of Continental Railway Solution, So this is actually a Bingo! moment. I was wondering where the locomotive may be, but was happy just picking up what I was seeing, and not looking for it.
